英文:
why is this showing a TypeError: View_Account.go_to_modify_account() missing 1 required positional argument: 'id'
问题
更新按钮不起作用的原因是在 self.modify_account 方法中，您尝试使用 id 参数，但没有为该方法提供该参数。这可能导致类型错误。
您可以尝试做以下修改，将 self.modify_account 方法修改为不需要参数的方法，然后在该方法内部获取选定行的 id：
def modify_account(self):
if not self.table.selection():
messagebox.showinfo('Update Account', 'Please select an account to modify')
else:
for selected_row in self.table.selection():
row = self.table.item(selected_row)
id = row['values'][0]
self.go_to_modify_account(id)
通过这种方式，modify_account 方法将从选定行中获取 id，而无需在方法调用时传递参数。这应该解决类型错误问题。如果仍然存在问题，请提供更多详细信息以供进一步帮助。

why does the update button not work. it shows type error
i tried adding self to the id but it still does not work

根据文档，command= 需要一个没有参数的函数。所以你使用 command=self.foo 意味着你将调用 self.foo()，并且没有 id 参数。
为什么你在 go_to_modify_account 中期望一个 id 参数，但在其他地方没有？你是不是想要使用 command=modify_account？
英文:
At least according to the documentation, command= takes a function that has no arguments. So the fact that you have command=self.foo means that you're going to end up calling self.foo() and there is no id argument.
Why are you expecting an id argument in go_to_modify_account but none of the others? Did you mean command=modify_account?
